Lua is a powerful light-weight programming language designed for extending applications. It is also frequently used as a general-purpose, stand-alone language. Lua is implemented as a small library of C functions, written in ANSI C, and compiles unmodified in all known platforms. The implementation goals are simplicity, efficiency, portability, and low embedding cost. The result is a fast language engine with small footprint, making it ideal in embedded systems too.
This is an older version of Lua needed only for compatibility with other programs such as Wireshark-4.2.2 and VLC-3.0.20.

Install Lua by running the following commands:
patch -Np1 -i ../lua-5.2.4-shared_library-1.patch &&
sed -i '/#define LUA_ROOT/s:/usr/local/:/usr/:' src/luaconf.h &&
sed -r -e '/^LUA_(SO|A|T)=/ s/lua/lua5.2/' \
-e '/^LUAC_T=/ s/luac/luac5.2/' \
-i src/Makefile &&
make MYCFLAGS="-fPIC" linux
The installation of this package is complex, so we will use the DESTDIR method of installation:
make TO_BIN='lua5.2 luac5.2' \
TO_LIB="liblua5.2.so liblua5.2.so.5.2 liblua5.2.so.5.2.4" \
INSTALL_DATA="cp -d" \
INSTALL_TOP=$PWD/install/usr \
INSTALL_INC=$PWD/install/usr/include/lua5.2 \
INSTALL_MAN=$PWD/install/usr/share/man/man1 \
install &&
install -Dm644 lua.pc install/usr/lib/pkgconfig/lua52.pc &&
mkdir -pv install/usr/share/doc/lua-5.2.4 &&
cp -v doc/*.{html,css,gif,png} install/usr/share/doc/lua-5.2.4 &&
ln -s liblua5.2.so install/usr/lib/liblua.so.5.2 &&
ln -s liblua5.2.so install/usr/lib/liblua.so.5.2.4 &&
mv install/usr/share/man/man1/{lua.1,lua5.2.1} &&
mv install/usr/share/man/man1/{luac.1,luac5.2.1}
Now, as the root user:
chown -R root:root install && cp -a install/* /
sed -i ... src/luaconf.h: This command changes the Lua search path to match the install path.
sed -i ... src/Makefile: This command deconflicts this installation with the latest version of lua.
